Hereditary Spherocytosis in the Neonatal Period: A Case Report.

Hereditary spherocytosis (HS) is the third most common yet most frequently underrecognized, congenitally acquired hemolytic disease of the neonate. Hereditary spherocytosis is caused by a defect of one or more erythrocyte membrane proteins, which leads to an increased rate of destruction of circulating red blood cells. The HS spectrum of symptoms is varied from asymptomatic to intrauterine hydrops.
